    Air powered closer for post vise ideas?

    There was also a design in the old Blacksmith's Journal from 15 years back or so. Smaller cylinder mounted vertically between the legs and used some sort of 4 bar linkage.

    Tire on a little giant?

    I'm a little underwhelmed with the control of that Beaudry above. It travels on another blow or 2 and it doesn't seem to be able to stop at the top of the stroke. When punching the hole he has to quickly pull the work out to avoid another hit rather than having the ram stop when wanted. The VFD might be great for starting and running the hammer, but I firmly believe all mechanicals need a brake to get optimal performance. The Beaudrys I've run had well tuned factory brakes and could start and stop on a dime. Even halfway thru a downstroke.

    New Mouse Hole Anvil

    Always good for a laugh! OP, that's a good anvil. Happy hammering.

    Steel and concrete anvil stand

    Perhaps not for direct contact between cast iron power hammer bases and concrete inertia blocks, but there is a fair amount of documented literature that uses concrete as the primary mass under power hammer bases. Often combined with oak boards/timbers and in the modern era Fabrika pads, but a concrete foundaition block is fairly standard for backing up a power hammer. Even little old Little Giants had factory literature showing size and bolt placement of the concrete block they recommended under the hammer. http://www.newenglandblacksmiths.org/little-giant/

    How much control on a power hammer?

    Well said. Tire hammers if built to Clay's design are just fine. If you have experience and want to step up to the next level, they are a great place to start. Fair warning, there is a serious rabbit hole you can fall down when it comes to power hammers! (grin)
  7. Slower rotation of the input changes the reaction of the springs and linkage. Slower rpm would degrade the performance of an antique mechanical. It's a dynamic system. And even an "art shop" needs to put product out the door to pay the bills, so running a hammer the way it was designed is advantageous. Mechanicals do tend to run faster than air hammers, but the bigger ones run slower than small ones typically. Thanks to SS for the link to the NEB website, you can find a bunch of info on antique hammer rpm there. Note that older motors had a little more copper in them so they were a little more robust when working on the bitter edge.

    Barbour Stockwell Beaudry 150

    Love Beaudrys but yeah, no love on the vid.
  9. Open up the space between the dies. Can you adjust the location of the eccentric?
  10. I've seen this hammer in person, and encouraged Bryan to buy it for a very reasonable price. The wedge(s) on the back of the lower die are 2 pieces, driven into the dovetail opposing one another. Look again at the pics above. Bad practice and that's a little troublesome , but the portapower, drilling it out, and comealongs (in order of precedence in my opinion) should work.
  11. I've actually made a bunch of these, and mild steel (what we call a-36 these days) works just fine. Didn't bother to google it, sorry.
  12. That's a Howe, patented as a St.Laurence hammer. Made in Rutland, Vermont. Quite rare, supposedly seriously solid industrial machines. 3 phase wouldn't stop me, easy enough to swap the motor or put on a phase converter.

    Need to know best U.S made propane forge companies

  14. This is awesome, keep it coming!
  15. Several possible causes in no particular order. To be more accurate we need to see pics (close ups) of the machine and its particular parts and the resulting work piece. 1. Ram (tup) guides too loose allowing the dies to shuck sideways upon impact. Even a little slop will start to affect the WP. 2. Dies not perfectly parallel. Could be in the machining of the dies, could be in the fit-up of the whole machine. 3. Operator error. Not rotating perfectly 90 deg. per turn or holding the stock out of level with the dies. Film yourself working with your phone, it'll be an eye opener. 4. Aysmetrically heated work. We need more info.
